M5lp 1111 Procharger Boss 302 Boost The Boss 008

A minimum 55 psi of static fuel pressure is required for making maximum horsepower with a power adder and a Boss’ stock, mechanical-returnless fuel system. Evolution Performance hops up factory injectors (47-lb/hr) to pump at a rate of 75 lb/hr, which seem to be the hot ticket for maintaining a smooth idle and good driveability for ’11-’12 5.0s with big superchargers.
